Hola! I aam planning on going to Mexico in September and teach for a year or two. I have been wanting to do this for so long, but I finally sold my place and decided to go for it!

I just have a couple of questions...has anyone taught in Mexico and Costa Rica and if so, which did they prefer and why?

Also, I wanted to know about the TESL certificate. I can get it here in Calgary (Canada) before I go, or I can get it in PV or Guadalajara. I can also get it outside of Costa Rica, but it is twice as much. If I get it in Mexico will I have a better chance of finding work? I have experience teaching ESL, just not the certificate.
